Battery Internal Resistance Detection with Adjustable Probes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery internal resistance detecting devices are limited to detecting the internal resistance of a single battery specification due to fixed probe positions, preventing the detection of batteries with different specifications.
Innovation Solution
The device features adjustable probes that can be positioned to match the varying distances between the positive and negative electrodes of different battery specifications, allowing for flexible and stable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the probe distance is fixed, then the device structure is simple, but the device can only detect batteries of one specification
Solution Approach 1:
The patent makes the probe distance adjustable by allowing the second probe to move along the electrode surface, transforming a static fixed-distance structure into a dynamic adjustable-distance structure. This enables the device to adapt to different battery specifications while maintaining operational simplicity through a straightforward sliding mechanism.
2Adaptability or versatility
If the probe distance is adjustable, then the device can detect batteries of different specifications, but the device structure becomes more complex
Solution Approach 1:
The patent divides the probe assembly into independent components: a first probe fixed at one end and a second probe that can be independently adjusted along the electrode surface. This segmentation allows each probe to be positioned separately, enabling flexible adaptation to different battery sizes without requiring complex coordinated adjustment mechanisms.
Solution Approach 2:
The patent changes the distance parameter between probes from a fixed value to an adjustable value. By allowing the second probe to be positioned at different distances from the first probe along the electrode surface, the device can accommodate batteries of various specifications while maintaining a relatively simple structural design.
